Solution

The correct option is B
480g

The balanced reaction for combustion of benzene is

$2 C_{6} H_{6} + 15 O_{2} \to 12 C O_{2} + 6 H_{2} O$

Therefore, 15 moles of oxygen gas is required for complete combustion of benzene.

We know that, $1 m o l e$ of $O_{2}$ = $32 g$

$∴$ $15 m o l e s$ of $O_{2}$ = $15 \times 32$ = $480 g$
